The table constitutes a list` of' items vor'ingredients showing `selected portions thereof land certain characteristics of theitems based on the selected portions. ,y

j The main purposejand object.v of the present inventionis to provide means whereby onemay quickly determine thef cumulative values of certainitems vappearing in the table device and inchosen quantities.

I `have chosen to Aexemplify my invention as l.means forfgraphically presentingthe nutritional f valueof `foods consumed, in anygiven period of time, 'e.fg.,a vd ay, :by yafperson typicalzjof one of several selected"classes,so thatk the, proper amount of "important constituents"of4 thejlfood may 'be eaten to `thereby maintain balancedidiets for persons of the selected classes.

vAnother `object of myY invention is5tov provide a combined compound s'cale-v and table of items so portion of thel amounts of certainfoods in a -certain time Will supply quantities of certain food constituents in sufficient amounts to meet certain standards ci sufficiency yfor certain types of persons. v

Further objects and advantages'of the inven tion will be apparent from the` descriptionand claims.

As herein exemplified, the invention is shown as set up to denote the minimum nutritional requirements and recommended nutritio-nal allowances, of certain important food constituents, forsix groups or classes of persons. These classes are (l) man, (72) woman, A(3)- pre-school-child, (f4) school child,l (5) fadolescent girl, and (6) adolescent boy. The nutritional requirements for the varyingages,` activities, land conditions ofl the personsyare. shown for the several groups.l

In order to make-clear the visualization, three zones have been established, represented by areas on the scale in the order named reading from the arranged that selected'values of said'items'may u be visually set upon the compound scalejand the' cumulative l[amounts of said values, as soset up,

of ydifferent colors on the chart and-designated,`

respectively, danger Zone,subsistence zone and adequate zone. These zones are arranged bottom up. Qn the slide member the lines separating the danger and subsistence zones or areas j represent the minimum requirements for every becoming available/for comparison vwith zones or predetermined maximum and minimum values for the said items. Y

A further Vobject"ofrlmy yinvention is to provide means for `quickly determining the adequacy of diet for persons 'of different sex and varying ages,

f activities and conditions.

A-stilliurther object of the invention is to provide means for" visually setting up the cumulativeA values of ycertain of the listed' items 'fora xed 1 `period ci ltinieto thereby enable av dietitian to A y adjust Athe dietvofsuch a person so as `to supply properY amounts'` of certain food 'constituentsl in that persons diet.

,Mywinvention has for an additional object theprovision'of -means iorv graphically representing the dangerous,HV minimum, and adequate `food valuesin'clu'ding certain selected constituents, for diets of persons to meet varying conditions` oi activity and in somev cases differences in age.

Fig. 9 is an enlarged view of part of the con-,- struction shown in Fig. 8.

The device includes the compound scale or indicating instrument A and the table or listB.

The compound scale as illustrated includes `a front member Land a back member 2 (Fig. 5), preferablyy of heavy paper or cardboard material. The back member extends below the compound scale, when the device is open, to constitute a support for the table. f

The device as illustrated is arranged in three panels with fold lines at 3 and 4 to fold into a substantially fiat shape convenient to place in a pocket.

The front member I is provided witha plurality of parallel 4slots 5 (Figmi) laterally spaced one Vfrom another and `arranged with their lengths transversely of the length of the front member. An endmost slot B is provided, parallel to the other slots for a purpose to be later described. The upper margin of the front member l as well as the back member 2 is serrated as at 1 to provide portions for securingirivets 8 as well as spaces 9 therebetween to expose the ends of the vertical slot slides for prehension. The righthand ends of the front and back members are notched as at ID to provide a space to grasp the horizontal slide member of the compound scale.

Next behind vthe front memberv I s aV Quid@ member ll (Fig. 4) provided with slots I2, open at -their upper ends, which lie behind the slots 5 of the front member and serve as guides i4 for the vertical slot slides I3. There is a slot I5 adapted to register with the slot 6 in the front member. A third member I6 lies behind the second member Il and is provided with slots I1 to register with the slots 5 in the front member, and a slot i8 to register with the slot 6 in the frontl member. The upper margin .of this member is provided with serrations I9 to correspond with those on the upper margin of the front member.

A fourth member 20 is disposed behind the member I6. This member has an upper portion 2l having similar serrations 22 along its upper margin, and a lower longitudinal portion 23. The major portion of this member is cut out and is fashioned with a notch 24 adjacent the upper left-hand corner.

The horizontal slide member 25 is shaped to iit 'within the cut out portion of the member 20 and isl provided with a lug 25 to lie withinthe slot 24. The lug 26 is in length less than the length of the notch, so that the slide 25 may have sliding movement, which movement is limited by engagement of the lug 25 with the ends of the notch 24.

At the left-hand end of the slide member 25 and crosswise of the member appear indicia as to the six classes of persons heretofore named, and arranged thereon in the following, order from left to right, adolescent boy, adolescent girl, school child, pre-school child, woman and manj and identiiied in Fig. 8 by reference characters 21, 28, 29, 33, 3| and 32, in the order named.

In the space 2l is additional'data identilied by the numeral 1,4 (not'shown) which applies to boys 13 to 15 years of age. The numeral 18 thereon applies to boys 16 to 20 years of age.

In the space 28 'is a numeral 18 (not shown) applying to girls 13 to 15 years of lage and a numeral 18 applying to girls 16 to 20 years of age. In the third space 29 is a numeral 8 (not shown) applying to a child 7 to 9 years of age and a numeral 11 applying to a child 10 to 12 years of age. In the fourth space 30 is a numeral 2 applying `to a child 1 to 3 years of age and a numeral 5 applying to a child 4 to 6 years of age. In the fifth space 3| is a letter V (not shown) meaning very active, a letter M meaning moderately active, a letter S meaning sedentary, .a letter L for during lactation and a letter P for during pregnancy.

In the last space 3| is aletterl .V for Very active, a letter Mfor moderately active, and a letter S for sedentary. Y

Along the length of the slide member 25 are columns of colored zones, the lowermost zones being red, the intermediate zones being yellow and the upper zones being blue.

In some of these columns appear the numerals and letters (not shown) appearing in the various six designations of classes of persons, the presence of such numerals or'letters indicating the maximum recommended food allowance in the adequacy zone.

The back` member 2, as heretofore. explained, extends ,below the compound scale, when the device is open, to constitute a backing for the table or list B.

I Referring to Figure 1, certain portions of one of the pages of` the list show a columnar arrangement with the foods listed in the first column, the weight in grams ofsuch foods in the second balanced accordingly.

ulabe'led for niacin, and slot 44 Vfor vitamin C.

Along the margins ofthe several slots appear indicia,- the indicia for allof the slots except number' 36, the calorie slot, representing grams.. The calorie slot 36 represents calories.

Between the slots 6' and the'slot 35are zones or .areas reading `from the bottom up as follows:

'45 danger zone,`46subsistence zone and 4I adequate' zone. These zones arel colored, respectively, red,yellow and blue, in the order named, to correspond with the color arrangement on'the slide member 25. y l

The several columns on the slide member 25 are colored as heretofore mentioned and vary in vertical'heightv (Fig. 8), the. variations applying to the threezones mentioned. andy graphically showing the comparative extent of the various jfood constituents mentioned inthe three zones. These heights have a denite relation to the vertical scales on the front member I l.

The lines V48 separating the blue from the yellow zones, that is, the danger zoney from thesubsistence zone, represent ther minimum requirement for every one of the food constituents designated on thecompound scale. The lines 49 separating the yellow zones from the blue zones represent,

vfor the major part,` the recommended allowances of the/various constituents as established by the Food and NutritionalBoard and the National Research Council and based onthe values of these constituents as the same appear in the tablev and arranged in columns underneath the designated y slotsin the front member. Y Fig. 2 shows the compound scale set up to show recommended diet for a moderately active man. In this gure the slide member 25 has been pulled tothe right to bring the word Man into register with the slot 6. Such movement of the slide member brings the corresponding colored columns on the slide member into register with the various slots so that the lines of demarcation Iand the difference in color of the zones on the backgound visible through the slots will be readily apparent. The slides I3 have been raised so that the lower margins thereof cumulatively show the total food values of the several constituents additively, as the .constituents of the several foods eaten are added up and the slot slides extended accordingly.-v It will thus be observed that a dietitian having manipulated the slot slides as exempliiied in Fig. 2,l will have before her a visual exposition of the food values eaten by the particular person for a day. Should the cumulative values of the several constituents appear in the subsistence zone, then any shortage of any such constituent should be'made up at the next meal.

Should the positions of the slot slides I3 indicatek that too much of one and not enough of another constituent has been eaten, an allowance for such fact may be made at the next meal and the diet Fig. 3 shows the compound scale set up to cumulatively illustrate the food values, of the foods enumerated immediately below the' compound scale, in accordance with the iigures there appearing. The food appearing on this portion of the table has been listed at random to show what a person may have had for breakfast and for lunch. The difference in food values between what is shown by the positions of the slot slides I3 with reference to the colored zones yon the slide member 25 may be utilized in planning the third meal for the day so that food furnishing the difference between what is shown by the lower ends of -the several slot slides and that indicated by the colored Zones on the slide member maybe made up at the evening meal. f

It will be observed, in referring to Fig. 3, that the food lvalues for the two 'meals are in the main short of the adequate Zone so that to maintain a balanced diet the deciency must be made up at the next meal.

Comparing the set-up shown in Figs. 2 and 3, it will b'e observed that if the set-up of Fig. 3

represents the'breakfast and lunch of a moderl lThe slide memberj2 5fis moved endwise until the division, 21 to 32, inclusive, designative of the class, becomes visible through the slot 6. Such movement of the slide brings the proper Zone expositionfor that person into register with the slots 5and manipulation of the slot slides I3 may then be made to visually set up the food eaten.

It is believed that the brief explanation just given will makev it-readily apparent to a dietitian that the numerals and letters in the various columns of the slide member 25 will 'by reference to the numerals and letters in the spaces 21 to 32, inclusive, connectv one with another.l

Further modifications will be apparent to those skilled inthe art and it is` desired, therefore, that 'the invention be ylimited only by the scope of the appended claims.

Having thus described my invention, what I `claim and desire to secure by Letters Patent is:
